AMD Ryzen 7 7730U vs AMD Ryzen 7 7735HS Comparison

Head-to-Head Benchmarks

The data is unambiguous: the AMD Ryzen 7 7735HS wins every single head-to-head benchmark recorded in the database, taking all 17 comparisons against the AMD Ryzen 7 7730U. There are zero wins for the 7730U in the entire comparison set. This is not a close contest, and the margins are substantial across nearly every category.

The largest gap appears in PassMark physics, where the 7735HS scores 1073 against the 7730U's 751, a 30% advantage. This is a strong indicator for workloads that rely on physics simulation, as the higher sustained power envelope allows the 7735HS to maintain performance under heavy threaded loads. The next biggest delta is in extended instructions, where the 7735HS posts 20050 versus 14619, a 27.1% lead. This category typically reflects AVX and similar instruction-heavy workloads, making the HS part notably better suited for scientific or encoding tasks.

In Cinebench R23 multi-core, the 7735HS scores 13106 against 10801.5 for the 7730U, a 17.6% advantage. The single-core delta in the same test is much smaller: 1546 versus 1454.5, a 5.9% lead. This pattern repeats across the other rendering and general-purpose benchmarks. In Geekbench multi-core, the 7735HS reaches 8114 versus 6565, a 19.1% gap, while single-core shows 1699 versus 1541, a 9.3% lead. The multi-core gaps are consistently larger than single-core gaps, which points to the 35W TDP and higher clock speeds of the HS part allowing it to stretch its legs when all cores are active.

PassMark integer math shows the 7735HS at 85309 versus 72352, a 15.2% lead, while floating-point math shows 47865 versus 38460, a 19.6% lead. Data compression favors the 7735HS by 23.3% (293278 versus 225023), and data encryption by 21.8% (18237 versus 14258). Random string sorting shows a 22.2% gap (30388 versus 23651). Prime number finding, a test sensitive to integer throughput, shows 59 for the HS versus 45 for the U, a 23.7% difference.

The smallest margin in the entire set is Cinebench R23 single-core at 5.9%, followed by Cinebench R15 single-core at 6.9% (248 versus 231) and PassMark single-thread at 8.9% (3296 versus 3004). These single-thread deltas are meaningful but modest compared to the 20-30% swings seen in heavily threaded or SIMD-heavy tests. The interpretation is straightforward: the architectural and power differences between the two parts matter most when the workload scales across cores.

The cumulative average benchmark scores reinforce the same story. The 7730U holds an average benchmark score of 25625, while the 7735HS sits at 25147. This is a curious inversion, given that the HS wins every head-to-head test. The explanation lies in the percentile rankings: the 7730U places in the 78th percentile of all CPUs, while the 7735HS places in the 77th. The difference is within one percentage point, and the nearest rival lists show both parts trading positions against nearby chips. The 7730U edges out the AMD Ryzen 5 6600H by 0.3%, the Intel Xeon D-2752TER by 0.4%, the AMD Ryzen 7 5700 by 0.4%, and the AMD Ryzen 5 7640U by 0.5%. The 7735HS trails the AMD Ryzen 9 6900HS by 0.5%, sits 0.2% behind the AMD Ryzen 7 6800H, and leads the AMD EPYC 9474F by 0.2% and the AMD Ryzen 5 8400F by 0.6%. The head-to-head wins for the HS are decisive, but in the broader CPU landscape, both parts occupy the same performance tier.

Where Each One Wins

The AMD Ryzen 7 7735HS wins in every recorded workload category, so the practical question is not which one wins a given task, but which one loses by the least. For users who primarily run lightly threaded applications, the 7735HS still leads, but the margin shrinks. Cinebench R23 single-core and R15 single-core show the smallest deltas (5.9% and 6.9% respectively), and PassMark single-thread shows 8.9%. If a workload is mostly single-threaded, the 7730U is comparatively closer to the HS part, though still behind.

For heavily threaded workloads, the HS part pulls away dramatically. PassMark physics shows a 30% gap, extended instructions 27.1%, data compression 23.3%, and random string sorting 22.2%. Users running rendering jobs, video encoding, scientific simulations, or any task that engages all 16 threads will see a much larger benefit from the 7735HS. The multithread score of 23166 versus 18037 (22.1%) and Geekbench multi-core of 8114 versus 6565 (19.1%) confirm that the HS part scales better with core utilization.

The 7730U does not have a single benchmark category where it beats the HS part. Its strength is contextual rather than absolute: it is a 15W part, and the data shows it lands within single-digit percentages of the HS in single-threaded tests while consuming substantially less power. For fanless or passively cooled ultraportables, that efficiency profile matters. The 7730U also supports DDR4 memory, which may align with existing platform costs, and it uses AMD Socket FP6 rather than the FP7 socket of the HS part. But in raw performance terms, the recorded data gives the HS part every win.

Specification Differences

The two CPUs share the same core and thread counts: 8 cores and 16 threads each. Both have 64 KB of L1 cache per core and 512 KB of L2 cache per core, with 16 MB of shared L3 cache. Both support ECC memory and have dual-channel memory buses. Both are actively produced mobile parts, and neither has an unlocked multiplier.

The differences start with clocks. The 7730U has a base clock of 2000 MHz and a boost clock of 4.50 GHz. The 7735HS has a base clock of 3200 MHz and a boost clock of 4.75 GHz. The HS part runs at a higher base clock by 1.20 GHz, which directly contributes to its multi-core advantage. The TDP also differs: the 7730U is rated at 15W, while the 7735HS is rated at 35W.

The sockets differ: the 7730U uses AMD Socket FP6, while the 7735HS uses AMD Socket FP7. The memory support differs as well: the 7730U supports DDR4, while the 7735HS supports DDR5. Memory bandwidth reflects this: the 7730U offers 51.2 GB/s, while the 7735HS offers 76.8 GB/s. The PCIe interface differs too: the 7730U provides Gen 3 with 16 lanes (CPU only), while the 7735HS provides Gen 4 with 20 lanes (CPU only).

The integrated graphics also differ. The 7730U pairs with Radeon Graphics (Vega 8), while the 7735HS pairs with Radeon 680M. The process nodes differ: the 7730U is built on 7 nm TSMC, the 7735HS on 6 nm TSMC. Die size differs slightly, with the 7730U at 180 mm² and the 7735HS at 210 mm². The transistor count is listed for the 7730U at 10,700 million, but is not recorded for the 7735HS. Release dates differ by a few months: the 7730U launched on January 3, 2023, and the 7735HS on March 31, 2023. Part numbers also differ, with the 7735HS having two listed part numbers (FP7 and FP7r2 variants).

Architecture Differences

The 7730U is built on Zen 3 architecture with the codename Barcelo-R, belonging to the Ryzen 7 (Zen 3 (Cezanne)) generation. The 7735HS uses Zen 3+ architecture with the codename Rembrandt-R, belonging to the Ryzen 7 (Zen 3+ (Rembrandt)) generation. Both are 7000 series mobile parts from AMD, but they represent different architectural revisions.

The process node difference is one nanometer: 7 nm for the 7730U versus 6 nm for the 7735HS, both fabricated by TSMC. The smaller node on the HS part does not translate into a smaller die, however. The 7730U measures 180 mm², while the 7735HS measures 210 mm². The larger die on the HS part likely accommodates the newer Radeon 680M integrated graphics and the DDR5 memory controller.

Cache architecture is identical in structure: 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. The memory subsystem differs at the protocol level: DDR4 versus DDR5, with the HS part offering 50% more memory bandwidth (76.8 GB/s versus 51.2 GB/s). This bandwidth advantage, combined with the higher base clock and Zen 3+ refinement, explains why the HS part excels in bandwidth-sensitive tests like data compression and encryption.

The PCIe generation also differs, with the 7730U limited to Gen 3 and the 7735HS offering Gen 4 with more lanes (20 versus 16). This affects expandability for storage and discrete GPUs, though the integrated graphics remain the primary display output for both. The 7730U's integrated solution is the older Vega 8, while the 7735HS uses the Radeon 680M, which is a newer design. Neither part has an unlocked multiplier, so overclocking is not supported for either.

The Verdict

The data supports a clear split based on workload and platform priorities. The AMD Ryzen 7 7735HS is the outright performance winner, taking all 17 head-to-head benchmarks. It leads by 30% in physics, 27.1% in extended instructions, 23.3% in data compression, and 22.1% in multithreaded PassMark. For anyone running rendering, encoding, simulation, or other multi-threaded tasks, the HS part is the correct choice. Its 35W TDP, higher base clock of 3200 MHz, DDR5 support with 76.8 GB/s bandwidth, and Zen 3+ architecture all feed into these results.

The AMD Ryzen 7 7730U is the efficiency-oriented alternative. It loses every benchmark, but the single-threaded deltas are much smaller: 5.9% in Cinebench R23 single-core, 6.9% in Cinebench R15 single-core, and 8.9% in PassMark single-thread. Its 15W TDP and DDR4 support make it a plausible choice for ultraportable designs where thermals and battery life take priority over peak throughput. The 7730U also carries a slightly higher overall percentile ranking (78th versus 77th) and a slightly higher average benchmark score (25625 versus 25147), which reflects its competitive standing against other CPUs in the database, but this does not change the head-to-head outcome.

Choose the 7735HS if the workload is multi-threaded, memory bandwidth matters, or the platform can support a 35W part. Choose the 7730U if the chassis demands a 15W part, the platform uses DDR4, or the workload is predominantly single-threaded where the performance penalty is smallest. The recorded data gives the HS part every performance win, but the U part remains a sensible pick for power-constrained designs where those wins are less relevant.
